interior of the' room, provided' with the usuai griile 'l1 and e register 12; 13 designotes arectungular grille for sir intake and 14 is o. circular grille through which the heated air radiates, regulated by u. register l5. i6 designates the heater housing, provided with an annuler basin 17, Substsn tialiy as shown in the drawings. i/.iounted Within sai housing are heating coils 18, comprising electrical resistance wires 19 secured around porcelain tubes 2O and cores 2i. Said coils are held in clamped position between an upper annuler plato sind ion/*er plate 23 by the rods @Li substantially es shown. Saidv upper annular plate is secured to iisnges 25 projecting downward from the grille 14 by Suitable fustcnings 26 es shown in 4. l

The conical disposition of the heating coils Within the housing is for the purpose of effecting a greater degree of eilioiency in nesting the air as it passes through the tem. The cooi sir is deliected to the lower port of the coils by. the wells of the reservoir Where it becomes heated, expands and rises in conformity with the divergence of the auxillery 4register Within seid room and' the register communicating with. the exterior of the house in the closed position. During Very coid Weather it is often desired to accelerate the heating of the room which is accomplished by opening Vthe auxiliary register, which will permit a larger volume of air to be conducted from the room through the heating system. During mild Weather, and at times when it is desired to freshen the sir Within the room, the register communicating with the exterior of the house is opened ailowing fresh air to be drawn into said room 'through the heater. It is obvious that both the auxiliary und the exteriorly communicating registers be kept open at one und the seine time.

From the above description taken in connection with. the accompanying drawings the edvsntoges of the .construction und of tile method. of operation of my electric heater will be readily apparent to those skilled in the art to which the invention relates, but, while l have described the prin ciple ot' operation ol' the invention. together with the device which l now consider to be the best embodiment thereof, I desire to have it understood that the heater shown is nierely illustrative and that such changes may he mad as are within the scope of tho following claims.

l. An electric heater comprising a housing; a grille for said housing having air intake openings t'orrned therein; a casing centrally disposed within the said housing adapted to t'orrn an air heating chamber, said casing associated with said housing forming a conduitI for Athe passage oil air to be heated; a container tor liquid Formed on said easing within said air l x.ating chamber; a downwardly converging heating element disposed within said air heating chalnber; a grille t'or said air heating chamber having air outlet. openings formed therein and controlling ineans for said openings.
